7130SA25J

Memory IC Overview

The Renesas Electronics Corporation 7130SA25J is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 52-pin PLCC package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access for two processors
• Asynchronous parallel interface for flexible system integration
• CMOS technology ensuring low power consumption during operation

Memory IC Applications

• Embedded systems requiring shared data buffers
• Telecommunications equipment signal processing
• Industrial control systems with multi-processor architectures

Memory IC Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted to surplus markets or existing stock. Verify RoHS compliance status carefully, as older batches may not meet current environmental standards. Confirm moisture sensitivity level handling requirements before procurement to prevent damage during assembly.

Memory IC Selection Notes

Select this part when a small-capacity, high-speed dual-port memory solution is required for legacy designs. Ensure the target application supports the 52-PLCC surface-mount form factor. Verify that the system logic levels are compatible with the specified 5V operating voltage range. Consider pinout compatibility if replacing similar devices from previous generations.

Memory IC Part Context

The 7130SA series belongs to Renesas' family of dual-port SRAMs designed for high-performance data buffering. This specific model offers 8Kb density, distinguishing it from higher-capacity variants like the 32Kb 7133SA series. It utilizes CMOS technology to balance speed and power efficiency in compact packages suitable for dense circuit board layouts.

Memory IC Replacement Considerations

Verify functional equivalence with IDT7130SA25J. Check pin compatibility and electrical specifications against other 8Kb dual-port SRAMs in 52-PLCC packages.
